Smallest.ai is an India-based voice AI platform offering ultra-fast, low-cost text-to-speech, instant voice cloning and voice agents via API, with strong multilingual and Indian-language support.

Smallest.ai focuses on speed and affordability in voice AI, built around models like Lightning, billed as one of the fastest TTS models available, and the Waves platform for studio-quality speech. It delivers sub-100ms response times suited to real-time conversational agents, along with instant voice cloning and support for 30-plus languages including strong coverage of Indian languages.
